In a successive Cournot oligopoly, we show the welfare effects of entry inthe final goods market with no scale economies but with cost difference between thefirms. If the input market is very concentrated, entry in the final goods market alwaysincreases welfare. If the input market is moderately...

We show the incentive for divisionalization by a monopolist producer. Incontrast to the previous literature, where divisionalization occurs for product marketadvantage, we show that divisionalization occurs if it provides strategic advantage inthe labor market. With unionized labor market, we...

We show the welfare effects of entry in presence of technology licensingunder Cournot competition. If the entrant is technologically inferior to that of theincumbent then, though licensing reduces (or completely eliminates) excessive entryfor relatively low entry costs, it creates excessive...

This paper considers the effects of entry in the final goods market when the input market is imperfectly competitive. We show that entry of a new firm may increase profit of the incumbent if the technology of the entrant is sufficiently inferior to that of the incumbent...

We show the effects of entry of a domestic firm and a foreign firm on welfare, in presence of licensing. In case of licensing with up-front fixed-fee, domestic entry increases welfare if the technological differences between the firms are not very large, whereas foreign entry increases welfare...

This paper shows that technology licensing may be socially undesirable. Possibility of licensing increases the incentive for entry and thus, increases competition. If technology of the incumbent and entrant is sufficiently close, licensing-induced entry reduces social welfare. Otherwise,...

In a vertically separated industry, where the input suppliers have significantmarket power, not only entry but also the markets (upstream or downstream) withentry possibilities might be a concern to the policy makers. While ‘entry in thedownstream market only’ always increases welfare,...

We show that a monopolist final goods producer may find it profitable to create competition by licensing its technology if the input market is imperfectly competitive. With a centralized union, we show that licensing by a monopolist is profitable under both uniform and discriminatory wage...
